ALBERT E. w. 'WYETH, on NEW-YORK, N. Y. ROLLER-SUPPORT FOR EDGEWISEMOVAB'LE oodRs AND TliACKS THEREFOR.

To all whom it mayicpncern;

Be it known that I, ALBERT E. W. .WY TH,

a citizen of the United States, residing. at

drawings.

New York, borough of. Brooklyn, in the In many largebuilding's-suchj asI. in churches,-.schools, and the1likeit is desirable to have betweenadj oiningrooms a very Wide doorway which is too wide to make itpracticable to employ a single door, and hence a pluralityof doors are.used, such doors in some constructions being hingedtogether and in otherconstructions a number.

of independent doors being employed.

My invention relates to the latter class and to the kind that areadapted when not in use for closing the doorway to bearranged side byside in a pocketand adapted to be run out from that pocket one after theother and by means of suitably-curved tracks adapted to be brought intoalinement. Such doors have heretofore in some instances been run intoand out of the pocket by means of overhead trolley-wheels suitablyconnected with the doors and traveling on curved overhead tracks. It ismore advantageous, however, in many instances that these large heavydoors be supported by and run upon wheels that travel upon track-railssunk in or laid upon the floor and at the same time have such wheels soattached to the door free to turn laterally when the door is being runover a curved portion of the track. I

It is the object of this invention to provide an improved constructionfor attaining this end, which object is accomplished by the devices andcombinations of devices shown in the drawings and hereinafterspecifically described. I

. That which I believe to be new will be v Specification'of LettersPatent.

Constructing the tracks to accomplish thisof course necessitates a curveineach one of them with the exception of one, and to prevent anybinding"or friction at such curved portions I provide the means about tobedescribed for attaching the carrying-wheels to the bottom ofthe door. j

-9 9 and 10 indicate a metal frame, the

parts indicated by 9 9 being metal plates and the part indicated by 10being a plate con- In the.

necting the side plates 9' together.

construction shown this plate 10 has its edges turned down at rightangles to form flanges.

11, which rest against the inner faces of the plates 9, through whichflanges and plates suitable rivets 12 pass to hold the platestotherefore, the bottom of the door is to be cut away transversely justsufficiently to provide a recess into which the plate-10 can project,

the depth of such recess being just sufficient to bring the lower edgesofthe side plates 9 in line with the lower edge of the door, and suchside plates 9 are then to be secured to the door by screws passingthrough them near their ends, as clearlyindicated by dotted lines inFig. 2.

It is evident from the foregoing that the Weight of the door will comeupon'the top I plate 10 of the frame 9 9 10 and that by makdoor is inuse.

ing the recess in the bottom of the door just long enough to receive thesaid plate and extending the side plates 9 considerably beyond the endsof such plate 10 a firm hold for the attaching-screws that pass throughthe plates 9 is afforded, and the recess will be hidden from view bythese plates when the I prefer to cut out the sides of the door at eachend of the recess to the thickness of the plates 9, as shown in Fig. 3so that the outer surfaces of such plates 9 will be flush with thesurfaces of the door.

13 indicates a wheel-frame, which in the form of construction shown isformed of a single piece bent to have two parallel vertical portionsconnected by a horizontal upper portion, between the depending parallelportions of which frame are secured axles 14, upon which are mountedwheels 15, adapted to run upon the tracks 8. The upper horizontalportion of the wheel-frame 13 is pivotally connected by a suitable pivot16 to the cross-plate 10, thus forming a swivel connection with thewheel-frame that permits it to turn as required when the wheels strikethe curve in the track. In the construction shown a washer is interposedbetween the under face of the plate 10 and the face of the horizontalpart of the frame 13, and to secure a wider bearing at the centralpivoted portion a portion of the material of the sides of the frame 13is cut out and struck up, as

shown. In practice it will be found best to provide each door with twosets of these swiveled truck-frames, one near each edge of the door.

It will of course be necessary to provide suitable means at the top ofthe door for affording lateral support; but I have not shown any suchmeans, as various devices may be resorted to for that purpose, and suchdevices "form no part of my present invention.

What I claim as new, and desire to secure by Letters Patent, is

The combination with a door provided with a recess in its lower edge,extending transversely entirely through the door, and a frame comprisingtwo side plates adapted to extend across and cover the marginal edges ofsaid recess and be attached to the faces of the door and a substantiallyU- shaped bridge-plate having its side ortions connected to said sideplates an fitting within said recess, of a wheel-frame of less widththan the recess, a swiveling connection between said wheel-frame andsaid bridgeplate, and wheels mounted in said frame, the axes of thewheels and the axis of the frame arranged at substantially right anglesto each other, substantially as described.
